Mailbox Lettering Review #22085: House numbers for our mailbox.

My wife decided to paint our mailbox since we were stuck at home due to covid-19 concerns. I wanted to put the house number on it in a nice readable font so I thought of vinyl cut lettering. I've used it on trade show booths for work before and it holds up pretty well for that but I'm not sure about being exposed to the elements. I coated the painted parts with liquid epoxy but not the numbers. I got several sets of the vinyl numbers while I was at it so if they come off, I will replace them and put epoxy on them too.
